| TDE1737 Interface circuit - relay and lamp-driver Features High output current Adjustable short-circuit protection Thermal protection with hysteresis to avoid the intermediate output levels Large supply voltage range: + 8V to +45V SO14 DIP-8 Description The TDE1737 is a monolithic amplifier designed for high current and high voltage applications, specifically to drive lamps, relays and control of stepper motors. This device is essentially blow-out proof. Current limiting is available to limit the peak output current to a safe value, the adjustment only requires one external resistor. In addition, thermal shut down is provided to keep the I.C. from overheating. If internal dissipation becomes too great, the driver will shut down to prevent excessive heating. The output is also protected against short-circuits with the positive power supply. The device operates over a wide range of supply voltages from standard 15 V operational amplifier supplies down to the single + 12 V or + 24 used for industrial electronic systems .
